COMBINED COTTON CHOPPER AND'CULTIVATORV.

SPECIFICATION forming part 0f Letters Patent NO. 416,880, dated December10, 1889. Application filed August 19, 1889. Serial klo. 321,316. (Nomodel.)

To all whom t may concern:

Be it known that I, BERNE WHiTEI-IEAD, a citizen of the United States,residing at Imbodenffin the county of Lawrence and State of Arkansas,have invented a certain new and useful Combined Cotton Chopper andlScraper; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto theaccompanying drawings, and to the letters of reference markedthereomwhich form a part of this specification. 4 A

The special object of my invention is to thin out a row of cotton plantsarid scrape each side of the row at a single operation.

Figure 1 of the drawings is a top plan view,

and Fig. 2 a vert-ical longitudinal section on dotted line t x. Fig. 3isa detail perspective of the blade.V

In the drawings, A represents the axle, on which rotate the wheels B Bwhen the vehicle is backed, but whiehwheels carry it around when thevehicle is moved forward by means of the paWls 1),.the latter being heldby the springs b in the teeth of a ratchet-wheel C, which is fast to theaxle.

D is a bevel spur-wheel fast tothe axle and meshing with another one E,which is'y ground and thus out up all undesirable plant growth. Withthis construction the beams M M may be turned by the driver up orlaterally.' This is done with the handles N N, by which the blocks G Gmay also be slid on the axle, so as to throw the blades L out of gearwith the driving mechanism, while the pivoting of these blocks on theaxle permits the vertical movement of the beams M.

O O are fixed collars on the axle A, and P a""yoke to which the pole IQis made fast, Vthe yoke being pivoted so as to turn on the axle as thepole is raised or lowered.

Before starting to work, one blade on each shaft K is brought oppositeto the other and the sprocket-chain adjusted, when the mal chine isready for use. The ground-wheels B B carry the axle around, which, bymeans i of intermediate mechanism, rotates the blades L. The latter cometogether in pairs, one of a pair on each shaft,'so as to meet in themiddle of the row at intervals, thus chopping out the vstalks intendedto be removed and leaving those which 4are meant to grow.` In this waythe plants are thinned by chopping out atintervals, while each side ofthe row is se f nicely scraped, the .weeds being thus eradi- 1 cated andthe crust of the soil broken up.V i

. Having thus described all that is necessary to a full understandin g'of -my invention, what I claim as new, and desire to protect byLetspur-wheels D, of the slidingblocks @havingv the fixed verticaltrunnions F, carrying the loose wheels H E, whereby the choppers may bemoved vertically, horizontallyto the right f or left, or rotated, as setforth. i y

In testimony whereof I affix my signature in presence of two witnesses.

'BERNE WHITEHEAD.
